Molecules in space

Do molecules behave differently in space? If they do, then we could conduct experiments in space involving molecules and maybe even discover something new.

Can you think of any special conditions in space - which you don't find on earth - that could have on effect on molecules?

From my perspective, the only thing which Earth lacks from earth is gravity. Gravity plays a major role in the various phenomenons which we observed from Earth. How gravity affects molecules is another question itself.

Taking the formula for potential energy :

P.E : mgh

since your gravity is 0, then the whole result would be 0, leading to 0 potential energy.

Thats what I believe.

That's the formula for GRAVITATIONNAL potential energy. It is true that, far from space bodyes like star or planet, u won't feel gravity.

That would affect the PHYSICAL behavior of molecules, yes. A liquid would just keep floating together by example...

But you have other kinds of potential energies or sources of energy. Here are a fex examples : chemical potential (the energy in the chemical bonds), thermal energy (heat, basically), radiant energy (radiations).

Do you think any of those could be applicable to our question?
